Is Samsung Testing a Premium Galaxy Smartphone?

A new Web posting has rumors flying about an improved version of Samsung's newly-released Galaxy S5 smartphone.

NEW YORK ( TheStreet) -- While Samsung's Galaxy S5 flagship smartphone was just released, there's word that an even better device is on the way -- a move that new S5 owners probably won't appreciate.

A number of online blogs have quoted sources discussing a new phone with model number SM-G906K which has been spotted on a manifest list of import/export devices coming into India for "research and development" purposes. That model number is rumored to be Samsung's upcoming "Galaxy S5 Prime." Samsung has a history of shipping new phone models to India for testing.

The Prime is thought to be a premium version of the just-released Galaxy S5 handset, which was reviewed here.

The Prime is expected to add a "2K" high-definition screen to the device as well as other improvements. Experts believe the new handset's screen will measure 5.25-inches with 1440 by 2680 pixels (QHD resolution), will be powered by a fast, 2.5 GHz Qualcomm (QCOM) Snapdragon 805 processor, 3 GB of RAM (matching Samsung's Galaxy Note 3 phablet), 32 GB of internal storage, 16 and 2 megapixels cameras and will be wrapped in an all-metal (possibly aluminum) outer shell. That new Snapdragon chip is reportedly capable of supporting up to 4K screen resolutions and 55-megapixel cameras.

For the record, those rumored specifications also match some of the numbers originally thought to be associated with Samsung's new Galaxy S5.

There's also speculation that a new phone with similar specs was recently spotted on a popular benchmark testing Web site.

According to the Zaruba Web site posting, four of the new phones were shipped into India last week for testing purposes. For customs, each handset was valued at just over $500.

Samsung has been rumored for months to be working on a super-premium line of smartphones but so far has revealed nothing officially. Speculators thinks Samsung could be announcing some sort of new devices as early as next month.

There is also the possibility that whatever these test units turn out to be they may never be released to the general public.
